In the game of Reversi (also known as Othello), your goal is to own more Reversi pieces than your opponent when all of the spaces have been filled. Each Reversi piece has a black and a white side. At the beginning of the game, four pieces are on the board; you must place your piece so that it "captures" the other player's pieces. For example, if your opponent (black) is next to one of your Reversi pieces (white), you can capture that Reversi piece by placing another white Reversi piece next to it. Controls: Mouse to place Reversi pieces.
